I'll give you an example — in Russia most of the hospitals don't have any pain medicine, they don't have any money. So if you're with kids with cancer, they can have metastases to the bone; which some say is the worst pain a human can experience. So a mother can be in a room with a child who hasn't stopped screaming in five months. ...85% of the time I walk in there as a clown they'll stop screaming."
